COFFEE-POT.

SPECIPIGATION forming part of Letters Patent No. 367,780, dated August 9, 1887.

Application filed March 1, 1887.

To aZZ whom, it may concern: I

Be it known that I, JEREMIAH BoUnrNor, a citizen of the United States, residing at Springfield, in the county of Sang amon and y the steam when it is desired to make the coffee mild, to allow the steam to have access both to the top and the bottom of the strainer when it is desired to make the coffee strong, to re tain the strainer in the coffeepot without the use of a spring, and to preserve all the aroma of the coffee, even if it has to be reheated. These objects I accomplish by means of the construction and novel arrangement of parts, hereinafter described, embraced in the appended claims, and illustrated in the accompa nying drawings,'in which- Figure 1 representsaperspcctive view of the improved coffee-pot. Fig. 2 represents acen tral vertical section of the same through the spout and steam-tube, showing the strainer and the removable partition and diaphragm in place. Fig. 3 represents a perspective view of the strainer. Fig. 4 represents a perspective view of the removable diaphragm and depending tube.

bottom of the coffee-pot.

Referring to the drawings by letter, A design'ates the body of the coffee-pot, having a flaring top and provided with the circumferential inwardly-projecting beads a a, for a purpose hereinafter explained.

, The sides of the coffee-pot converge from its upper edge to the upper bead, at, below which the body is cylindrical as far down as the bead a, and below the latter the sides diverge to the Bis thesp.out, of ordinary construction, running upward from near the bottom of the body, and having a hinged lid .or cover, I), at its upper end.

I) is a handle secured on the side opposite the spout, and G is a pipe running from apoint just below the-lower bead,-a, to a pointjust below the upper edge of the body, and serving a purpose hereinafter explained.

Serial No. 229,342. (No model.)

and material-such as cotton or woolen cloth or woven wire'--and secured at its upper edge to the wire ring (I, which, when in place, rests upon the upper bead, a, the flared mouth of the coffee-pot permitting the strainer to be readily put in place and removed. The bottom of the strainer, when in place, is situated just above the removable diaphragm E, the edge of which rests uponand is supported by the lower bead,

a. The said diaphragm is concave above as it converges downward to the upper end of the vertical tube 0, which is secured to the central part of the diaphragm, with its lower end a short distance only above the bottom of the coffee-pot. c is a curved handle having its ends secured to the upper surface of the diaphragm on each side of the mouth of the tube 6, and serving to place and remove the dia ph ragm. F is the lid of the coffee-pot, of usual shape and eonstruction,-but preferably tapering upward or conical, as shown in the drawings.

To make mild cdffee, the strainer and dia phragm are put in place, the coffee ground very fine and put in the strainer, and boiling Water poured upon the coffee. The said water percolates through the coffee, extracts some of the strength and aroma thereof, falls upon the diaphragm, and is directed thereby to the mouth of the tube a, down which it descends, and, accumulating in the lower part of the coffee-pot, seals the lower end of the said tube, so that if heat is applied to the bottom of the coffee-pot the steam has no escape but up through the tube 0 to the upper part of the coffkzepot,

where it is condensed by the lid F and falls as hot water upon the coffee to again percolate throughthe same, gain strength therefrom, and descend through the tube 0 to the lower part of the coffee-pot. The steam will pass up the tube 0 when the water is low in preference to escaping through the spout, for the reason that it would have to raise the lid of the latter, which lid is weighted, and because the condensation in the upper part of the coffee pot forms a partial vacuum therein. Should the pressure in the coffee-pot become too great, a portion of the steam will escape through the spout.

As there is no communication with the open air when the coffeepot is closed and is being used, the aroma will be preserved, even should the coffee become cold and be reheated.

To make very strong coffee, the diaphragm is removed, the boiling water pereolated through the coffee, as before, and the coffee-pot placed over the fire. Apart of the steam will then rise up to the strainer and a part ascend through the tube 0 to the upper part of the same, so that the coffee is surrounded and penetrated by steam, and all its strength and aroma thereby extracted.

Having described my invention, I claim-- 1. A coffee-pot having a steam-pipe, opening into the upper and lower ends thereof, and a removable diaphragm suspended in the lower portion of the pot at a point above the lower end of the stea1n-tube, and having a tube depending therefrom, the lower end of said tube terminating a suitable distance above the bottom of the pot to becomeimmersed in theliquid therein, and thereby form a water seal joint, substantially as described, for the purpose set forth.

2. A coffee-pothaving the inwardly-projeetin g beads (t a, fOIlllGd therein at different points of its height, a strainer having the ring fitting on the upper head, a, and thereby suspended in the upper part of the pot, a concave diaphragm resting on the lower bead, a, and thereby removably suspended in the pot below and out of contact with the strainer, avertical tube depending centrally from the diaphragm and terminating ata suitable distance above the bottom of the pot, and thereby adapted to be immersed in the liquid therein, and the steam-pipe communicating with the pot at points above the strainer and below the diaphragm, substantially as described.

In testimony that I claim the foregoing as my own I llflNG hereto affixed my siguatu re in 40 presence of two witnesses.

JEREMIAH BOUDINOT.
